Re: ADI flash or Preflash TTL for non 'D' lenses?

On a NON "D" lens you're suppose to set the camera to PRE-FLASH TTL and not ADI. On this setting with NON D lenses the FLASH exposure is suppose to be much better and more accurate than ADI FLASH.

The ADI setting works with the "D" encoded lenses and the lens will provide the camera feedback distance data and so the camera will be able to better calculate the amount of FLASH (light) needed by the flash without pre-flash TTL metering. However, this mode only works when the flash is DIRECTLY aimed at the subject (no diffuser) and must not be bounced. As the previous poster has suggested on most occassions the exposure between the ADI and PRE-FLASH TTL aren't very different.

Hope this helps.


From the minds of Minolta to the imagination of Sony, Alpha, like no other.
